IMPORTANT SAFETY INSTRUCTIONS

(SAVE THESE INSTRUCTIONS)

WARNING

To reduce the risk of fire, electric shock, serious injury or death to persons when using your tumbler, follow these basic precautions:

1. Read all instructions before using the tumbler.

2. Refer to the GROUNDING INSTRUCTIONS for the proper grounding of the tumbler.

3. Do not dry articles that have been previously cleaned in, washed in, soaked in, or spotted with gasoline, drycleaning solvents, other flammable or explosive substances as they give off vapors that could ignite or explode.

4. Do not allow children to play on or in the tumbler. Close supervision of children is necessary when the tumbler is used near children. This is a safety rule for all appliances.

5. Before the tumbler is removed from service or discarded, remove the door to the drying compartment.

6. Do not reach into the tumbler if the cylinder is revolving.

7. Do not install or store the tumbler where it will be exposed to water and/or weather.

W054

8. Do not tamper with the controls.

9. Do not repair or replace any part of the tumbler, or attempt any servicing unless specifically recommended in the User-Maintenance instructions or in published user-repair instructions that you understand and have the skills to carry out.

10. Do not use fabric softeners or products to eliminate static unless recommended by the manufacturer of the fabric softener or product.

11. To reduce the risk of fire, DO NOT DRY plastics or articles containing foam rubber or similarly textured rubberlike materials.

12. Always clean the lint filter before every load. A layer of lint in the filter reduces drying efficiency and prolongs drying time.

13. Keep area around the exhaust opening and adjacent surrounding area free from the accumulation of lint, dust and dirt.

14. The interior of the tumbler and the exhaust duct should be cleaned periodically by qualified service personnel.

15. If not installed, operated and maintained in accordance with the manufacturer’s instructions or if there is damage to or mishandling of this product’s components, use of this product could expose you to substances in the fuel or from fuel combustion which can cause death or serious illness and which are known to the State of California to cause cancer, birth defects or other reproductive harm.

16. Tumbler will not operate with the loading door open. DO NOT bypass the door safety switch by permitting the tumbler to operate with the door open. The tumbler will stop tumbling when the door is opened. Do not use the tumbler if it does not stop tumbling when the door is opened or starts tumbling without pressing or turning the START mechanism. Remove the tumbler from use and call the serviceman. Tumbler will not operate with lint panel open. DO NOT bypass lint panel safety switch by permitting the tumbler to operate with the lint panel open.

M414545

17. Do not put articles soiled with vegetable or cooking oil in the tumbler, as these oils may not be removed during drying. Due to the remaining oil, the fabric may catch on fire by itself.

18. To reduce the risk of fire, DO NOT put clothes which have traces of any flammable substances such as machine oil, flammable chemicals, thinner, etc. or anything containing wax or chemicals such as in mops and cleaning cloths, or anything dry-cleaned at home with a dry-cleaning solvent in the tumbler.

19. Use the tumbler only for its intended purpose, drying fabrics.

20. ALWAYS disconnect the electrical power to the tumbler before servicing. Disconnect power by shutting off appropriate breaker or fuse.

21. Install this tumbler according to these INSTALLATION INSTRUCTIONS. All connections for electrical power, grounding, and gas supply must comply with local codes and be made by licensed personnel when required. Do not do it yourself unless you know how!

22. Remove laundry immediately after the tumbler stops.

23. Always read and follow manufacturer’s instructions on packages of laundry and cleaning aids. Heed all warnings

or precautions. To reduce the risk of poisoning or chemical burns, keep them out of reach of children at all times (preferably in a locked cabinet).

24. Do not tumble fiberglass curtains and draperies unless the label says it can be done. If they are dried, wipe out the cylinder with a damp cloth to remove particles of fiberglass.

25. Always follow the fabric care instructions supplied by the garment manufacturer.

26. Never operate the tumbler with any guards and/or panels removed.

27. DO NOT operate the tumbler with missing or broken parts.

28. DO NOT bypass any safety devices.

29. Failure to install, maintain, and/or operate this machine according to the manufacturer’s instructions may result in conditions which can produce bodily injury and/or property damage.

30. Run tumbler with a load before putting tumbler into service.

The lint panel door will have to be removed in order to remove the two front capscrews.

NOTE: Do not throw these four capscrews away — they are the leveling legs.

Screw the four leveling legs back into the level adjusting fittings from the top.

Slide the tumbler to its permanent location and level. Keep the tumbler as close to the floor as possible. The tumbler must rest firmly on the floor so weight of tumbler is evenly distributed. Tumbler must not rock.

Each tumbler should be leveled within 1/8 inch (3.2 cm) from front to rear, and 1/8 inch (3.2 cm) from side to side. Check front to rear level by rotating the clothes cylinder until one rib is at the bottom, then place a level on the rib. Side to side level should be checked by placing a level on the front and rear of the top panel.

TUMBLER ENCLOSURE CONSTRUCTION

IMPORTANT: DO NOT block the airflow at the rear of the tumbler with laundry or other articles. Doing so would prevent adequate air supply to the combustion chamber of the tumbler.

A typical tumbler enclosure is shown in Figure 2. Note that the enclosure touches the tumbler top and side

To reduce the risk of serious injury, install lockable door(s) to prevent public access to rear of tumblers.

panels. Also, note the minimum and maximum dimensions. Be aware that there may be local codes and ordinances which must be complied with.

IMPORTANT: Install tumblers with sufficient clearance for servicing and operation. Refer to

FACILITIES REQUIRED

To assure compliance, consult local building code requirements.

WARNING

A drying tumbler produces combustible lint. To reduce the risk of fire, the tumbler must be exhausted to the outdoors.

W057

FLOOR

The tumbler must be installed on a level floor capable of supporting 100 pounds per square foot (488.3 kg/sq. m). Floor covering materials such as carpeting or tile must be removed.

LAYOUT

Whenever possible, tumblers should be installed along an outside wall where duct length can be kept to a minimum, and make-up air can be easily accessed. Construction must not block the airflow at the top rear of the tumbler. Doing so would prevent adequate air supply to the tumbler’s combustion chamber.

VENTING

For maximum efficiency and minimum lint accumulation, tumbler air must be exhausted to the outdoors by the shortest possible route.

Proper sized exhaust ducts are essential for proper operation. All elbows should be sweep type. Exhaust ducts must be assembled so the interior surfaces are smooth, so the joints do not permit the accumulation of lint. Do not use sheet metal screws to join vent sections. Improperly sized or assembled ductwork causes excess back pressure which results in slow drying, lint collecting in the duct, lint blowing back into the room, and increased fire hazard.

preferred to exhaust tumbler(s) individually to the outdoors. At no point may the cross area of installed

venting be less than the cross area of the exhaust thimble of the tumbler.

The maximum allowable length venting is 14 feet (4.3 m) and two 90° elbows or equivalent. If the equivalent length of a duct required for an installation exceeds the maximum allowable equivalent length, the diameter of a round duct must be increased by 10% for each additional 20 feet (6.1 m). Cross section area of a rectangular duct must be increased by 20% for each addtional 20 feet (6.1 m). To determine equivalent venting, Refer to Tabl e 1 .

Example: A 12" diameter duct’s equivalent length of 14 feet of duct and two 90° elbows is:

Equivalent Length = 14 feet + (2) 90° elbows

With the tumbler in operation, airflow at any point in the duct must be at least 1200 feet per minute (366 m./ min.) to insure that the lint remains airborne.

EQUIVALENT LENGTH OF

STRAIGHT DUCT

One 90° elbow = 7 feet (2.1 m) One 90° elbow = 9.3 feet (2.83 m) One 90° elbow = 11.6 feet (3.5 m) One 90° elbow = 14 feet (4.3 m) One 90° elbow = 16 feet (4.9 m) One 90° elbow = 18.7 feet (5.7 m)

One 90° elbow = 21 feet (6.4 m)

Table 1

= 14 feet + 14 feet + 14 feet = 42 feet (12.8 m)

Exhaust ducts shall be constructed of sheet metal or other noncombustible material. Such ducts must be equivalent in strength and corrosion resistance to ducts made of galvanized sheet steel not less than

0.0195 inches (0.495 mm) thick.

Where the exhaust duct pierces a combustible wall or ceiling, an opening having a diameter of 4 inches (10.2 cm) larger than the diameter of the exhaust duct shall be provided, with the duct centered in the opening. When ducts pass through walls, ceilings, floors or partitions, the space around the duct shall be sealed with noncombustible material. Refer to Figures 3, 4 and 5.

• Individual Venting

For maximum efficiency and performance, it is

20 M414545

• Collector Venting

While it is preferable to exhaust tumblers individually to the outdoors, a main collector duct may be used if it is sized accordingly. Refer to Figure 5. This illustration indicates minimum diameters, and should be increased if the collector length exceeds 20 feet (6.1 m). The collector duct may be rectangular in cross section, as long as the area is not reduced. Provisions should be made for lint removal and cleaning of the collector duct.

The collector duct must be tapered. Refer to Figure 5. The individual tumbler ducts must enter the collector duct at a 45° angle in the direction of airflow. Never

connect a tumbler duct at a 90° angle to the collector duct. Doing so will cause excessive back pressure, resulting in poor performance. Never connect two tumbler exhaust ducts directly across from each other at the point of entry to the collector duct.

The collector system must be designed so the static back pressure measured 12 inches (30.5 cm) from the exhaust thimble does not exceed the maximum allowable pressure specified on the installation sticker on the rear of the tumbler. This must be measured with all tumblers running that are vented into the collector.

At a minimum, the National Fuel Gas Code requires tumblers to have at least one square inch (6.5 sq. cm) of opening for every 1000 BTU/hr. of input rating for proper combustion.

Example: A tumbler with a rated input of 120,000

BTU/hr. requires 120 square inches of free opening.

The additional opening recomended by the manufacturer is required for optimum drying and reliability.

Protective louvers in the opening to the outdoors can reduce air movement by approximately 40 percent. The opening must compensate for the area taken up by the louvers.

The make-up air openings for a room containing tumbler(s) and/or gas fired hot water heater or other gravity vented appliances must be increased sufficiently to prevent downdrafts in any of the vents when all tumblers are in operation. Do not locate gravity vented appliances between tumbler(s) and make-up air openings. If it is necessary to duct make-up air to the tumbler(s), increase the area of the duct work by 25 percent to compensate for any restriction in air movement.

MAKE-UP AIR

A tumbler is forced air exhausted and requires provisions for make-up air to replace the air exhausted by the tumbler.

IMPORTANT: Do not obstruct the flow of combustion and ventilation air.

Recommended make-up air opening to the outside is 144 inches

(928 cm2).

M414545

WARNING

Solvent gases and vapors from dry cleaning machines create acids when drawn through the heater of a drying tumbler. These acids are corrosive to the drying tumbler as well as to the laundry load being dried. Be sure make-up air is free of solvent gases and vapors.

If the dry cleaning machines are in the same area as the tumbler, then the tumbler make-up air must come from a source free of solvent gases and vapors.

W058

FOR BEST PERFORMANCE provide an individual exhaust duct for each drying tumbler. Do not install a hot water heater in room containing drying tumblers. It is better to have the water heater in a separate room with a separate air inlet.

To reduce the risk of fire and accumulation of combustible gases, DO NOT exhaust tumbler air into a window well, gas vent, chimney or enclosed, unventilated area such as an attic wall, ceiling, crawl space under a building, or concealed space of a building.

W059

NOTE: Do not install wire mesh or screen in this opening as lint will build up and prevent proper discharge of air from drying tumblers.

GAS REQUIREMENTS

WARNING

To reduce the risk of fire or explosion, DO NOT CONNECT THE GAS LINE TO THE TUMBLER IF THE GAS SERVICE IS NOT THE SAME AS THAT SPECIFIED ON THE TUMBLER SERIAL PLATE! It will first be necessary to convert the gas burner orifice and gas valve. Appropriate conversion kits are available.

W060

IMPORTANT: Any product revisions or conversions must be made by the Manufacturer’s Authorized Dealers, Distributors or local service personnel.

WARNING

The tumbler and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.45 kPa).

The size of gas service pipe is dependent upon many variables (lengths, tees, etc.). Specific pipe size information should be obtained from the gas supplier. Refer to Ta b le 2 for general pipe size.

A dirt and water vapor pipe trap must be furnished and installed by customer. Refer to Figure 6.

It is important that equal pressure be maintained at all tumbler gas connections. This can best be done by installing a one inch (2.54 cm) pipe gas loop. Refer to

Figure 7.

WARNING

To reduce the risk of fire or explosion, if the tumbler is to be connected to Liquefied Petroleum (L.P.) gas, a vent to the outdoors must be provided in the room where the tumbler is installed.

W062

NATURAL GAS service must be supplied at 6-1/2 ± 1-1/2 inch water column pressure (1.62 ± .37 kPa).

L.P. GAS service must be supplied at 11 ± .3 inch water column pressure (2.74 ± .07 kPa).

The tumbler must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressure equal to or less than 1/2 psig (3.45 kPa).

IMPORTANT: The installation must comply with local codes or, in the absence of local codes:

• with the latest edition of the “National Fuel Gas Code”, ANSI Z223.1 in the U.S.A.

• with CAN1-B149.1 or CAN1-B149.2 in Canada

STEAM REQUIREMENTS (Steam Drying Tumblers)

The size of the steam service pipe is dependent upon many variables (length, tees, high pressure system, low pressure system, etc.). Specific pipe size information should be obtained from the steam system supplier or a qualified steam fitter.

1. Refer to Figure 9 for proper steam pipe configurations.

2. To prevent condensate draining from headers to tumbler, piping should have a minimum 12 inch rise (30.5 cm) above respective header. Do not make steam connection to header with a horizontal or downward facing tee or elbow.

3. Whenever possible, horizontal runs of steam lines must drain, by gravity, to respective steam header. Water pockets, or an improperly drained steam header will provide wet steam, causing improper operation of tumbler. If pockets or improper drainage cannot be eliminated, install a bypass trap to drain condensate from the low point in the steam header to the return.

4. In both steam supply and steam return line, it is recommended that each have a pipe union and globe valve. This will enable you to disconnect the steam connections and service the tumbler while your facility is in operation.

5. Before connecting trap and check valve to tumbler, open shut-off valve in steam supply line and allow steam to flow through tumbler to flush out any dirt and scale from tumbler. This will assure proper operation of trap when connected.

6. After flushing system, install vacuum breaker, bucket trap (with built-in strainer) and check valve. For successful operation of tumbler, install trap 18 inches (45.7 cm) below coil and as near to the tumbler as possible. Inspect trap carefully for inlet and outlet markings and install according to trap manufacturer’s instructions. If steam is gravity returned to boiler, omit trap but install vacuum breaker and check valve in return line near tumbler.

PIPING RECOMMENDATIONS

1. Trap each steam coil individually. Always keep the trap clean and in good working condition.

2. When tumbler is on the end of a line of equipment, extend header at least 4 feet (1.2 m) beyond tumbler. Install shutoff valve, union, check valve and bypass trap at end of line. If gravity return to boiler, omit trap.

3. Insulate steam supply and return line for safety of operator and safety while servicing tumbler.

4. Keep tumbler in good working condition. Repair or replace any worn or defective parts.

NOTE: Steam heated tumbler models are not certified by the American Gas Association or the Canadian Gas Association.

WARNING

The flexible steam hoses connecting the coil outlet connections and steam traps must have a minimum of 172 psig (pounds per square inch gauge) (12.04 kg/sq. cm) working pressure. A shut-off valve must be installed downstream from each steam trap so the condensate return line can be isolated in event a steam trap requires maintenance.

W064

STEAM VALVE ELECTRICAL CONNECTIONS

Refer to wiring diagram for steam valve electrical connections in J-Box.

7. Install union and shut-off valve in return line and make final pipe connections to return header.
